Luigi's death glare moves 885,000 US Mario Kart copies

C'mon, you're going to tell me that's not what's doing it? What, is it that Mario Kart 8 is fun? That it's familiar? That it's a Mario Kart game? Nope. All Luigi, baby. That's what you get in 2 anno Luigi.

No matter the cause, Mario Kart 8 is doing well. Total sales crossed 2 million three weeks ago. It sold 470,000 units in the US in June, making it the month's top seller and bringing its US total alone to over 885,000.

Even the Wii U's faint heartbeat is increasing its frequency. Nintendo says sales of hardware and software in June 2014 were up 233% and 373%, respectively, over June 2013. Wii U hardware sales are up 48% for the first half of 2014 compared to last year, and software sales are up 129%.
